Fig. 5 has shown the details of the support ring of Fig. 2 with the form of top view and partial cross section figure.
Embodiment
Fig. 1 has shown the wind turbine 1 that has blade 2, and this blade can rotate around the spin axis of approximate horizontal.The Bearing Installation of supporting rotating shaft and blade 2 is in outer cover 3, and this outer cover is installed in the top of pylon 6.Base 11 support tower 6, and the bearing 10 between base 11 and pylon 6 makes it possible to rotate pylon 6, so that blade 2 can be towards wind.Support ring 4 is around pylon 6, between outer cover 3 and ground roughly half is highly located, and this support ring 4 keeps pylons 6 to be in upright position.In an illustrated embodiment, four leg 5 supported rings 4 also are positioned at roughly half height of outer cover 3 with support ring 4, preferred heights between the height of outer cover 3 1/3rd to 2/3rds between.In other embodiments, the number of leg 5 can be three or five or more.
The lower end that leg bearing 7 supports and keeps a leg 5, the upper end of this leg 5 is fixed on the support ring 4.Leg bearing 7 is positioned at the distance that leg 5 with respect to the horizontal plane has angle [alpha] around base 11, and wherein, the preferred leg angle [alpha] for example is approximately 70 degree between 60 to 80 degree.Leg bearing 7 and leg 5 are designed to them can apply pulling force and thrust to support ring 4.Support ring 4 keeps the horizontal force on vertical and the support ring 4 to make it possible to design a cylindrical steel pylon 6 with less maximum diameter in the structure that the about 70 leg angle [alpha] of spending are directed by leg 5 pylon 6.
The power that is produced by the wind on blade 2, outer cover 3 and the pylon 6 is passed to leg bearing 7 and ground by support ring 4 and leg 5, and does not introduce bending moment in the bottom of pylon 6.Bending moment in the pylon 6 has maximum value in support ring 4 vicinity.This makes near the pylon 6 of vicinity at top of the pylon 6 of diameter place, the bottom of pylon 6 is equal to or less than outer cover 3 become possibility.Cylindrical pylon 6 with diameter of constant is possible.
In the bottom of pylon 6, the base 11 that has bearing 10 is with pylon 6 rotatable mode support tower 6.In order to rotate pylon 6, exist driver 28.In order to stablize the rotational position of pylon 6, driver 28 can be self-locking, perhaps, exists the independently break that is used for pylon 6 is positioned at the rotational position place of an appointment.Suitable self-locking driver 28 is a worm gear drive, and can be applicable to this type of situation: driver 28 is approaching to safeguard because of being easy near ground.In order to enter the inside of pylon 6, pylon has and can pass through platform 9 and approaching door 8.
In an embodiment of pylon 6, outer cover 3 is positioned at 100 meters height place on the ground, and the blade 2 of wind turbine 1 has 50 meters diameter.Wind turbine 1 produces the power of 1 megawatt and can apply 250,000 newton's horizontal force.Because support ring 4 supports pylon 6 at about 40 to 50 meters height place from side collateral branch, thereby the diameter of pylon 6 can be less than 3.50 meters.This road transport that makes it possible to be assembled into the support ring of pylon 6 becomes possibility.
Be used in concrete application that transmission is positioned at pylon 6 by wind turbine 1 energy-producing equipment and along with pylon 6 rotation, thereby avoided complicated cable or line.This equipment can be arranged in outer cover 3, this equipment for example for the generator that is used to produce electric power, be used to produce the pump of hydraulic power or be used to compress or the compressor of liquid gas.In another embodiment, this equipment is positioned at the bottom of pylon 6, so that the maintenance of equipment is more prone to.Under latter event, can carry out angle transmission (angular transmission) at the top of pylon 6, thereby the running torque of the horizontal axis that blade 2 is driven is transferred on the vertical shaft of the length of pylon 6.
Fig. 2-5 has shown and is installed in the support ring 4 and is connected to the outer surface of pylon 6 and the roller 12 that rolls.These rollers 12 remain on its vertical position with pylon 6.At the height place of support ring 4, the wall 25 of pylon 6 has the columniform ring 24 of an enhancing, has increased the thickness of wall, wherein, strengthens ring 24 and can have reinforcing portion 26.Roller 12 rotates around wheel shaft 18 and have a bearing 27 between roller 12 and wheel shaft 18.Wheel shaft 18 is installed on the frame plate 13, and wherein, in each frame plate 13, two wheel shafts 18 are installed in the equidistant place of 17 of spin rotating shafts.Two frame plates 13 that are positioned at the both sides of two rollers 12 can connect, to form a framework (not shown).Running shaft 17 is installed in the rotating frame 16, and wherein, each rotating frame 16 has two running shafts 17 at the equidistant place from gimbal axis 15.Gimbal axis 15 is installed in the corner 14 near the support ring 4 of leg 5.Running shaft 17 has the lockplate 23 that is used for locating vertically.In an illustrated embodiment, from the power on the axle 17 of acting in the corner 14 of support ring 4 by five equilibrium on four rollers 12.In other embodiments, can have more or less roller 12 that is connected on running shaft 17 and/or the support ring 4, wherein, this design will make all rollers 12 load about equally and the difference of the load on the roller 12 for minimum.
It is cylindrical strengthening ring 24, makes the pressure of 12 pairs of rings 24 of roller not change during the rotation of pylon 6.In an illustrated embodiment, the wall 25 of pylon 6 also is roughly cylindrical.In other embodiments, being higher or lower than the shape of the pylon 6 of cylindrical ring 24 can be different.For example, wall 25 can be polygonal, to simplify the production of wall 25.
It is adjustable that roller 12 is being pressed the power that strengthens ring 24.This adjusting can obtain in a number of ways, for example, by gimbal axis 15 is positioned in the slotted hole (not shown), rather than in the circular hole, and with the spring (not shown) gimbal axis 15 is pressed to and to strengthen ring 24.Fig. 2 has shown another embodiment, wherein, can change the contour of support ring 4.Between two positions of installation frame axle 15, support ring 4 is interrupted by slit 30.Flange 20 is positioned at the both sides in slit 30.Flange 20 is connected with nut 22 by the tension rail 21 that has head 19.If necessary, can between head 19 or nut 22 and flange 20, the spring (not shown) be set.The shortening of tension rail 21 has increased roller 12 and has strengthened the pressure that encircles between 24.
Worm drive 28 shown in Fig. 1 is to be used for one of embodiment who rotates towards wind by wind turbine 1.Fig. 2 has shown roller driver 29 with dotted line, and this roller driver is connected on one of them above roller 12 and can rotates pylon 6.In order to keep wind turbine 1 along specific direction, roller driver 29 is provided with the break (not shown).
Roller or take turns 12 and be the steel of bulk or composite, or for having the steel of bulk rubber or polyurethane tire (not shown).Cover the periphery that strengthens ring 24 in the mode that prevents corrosion.May can be ceramic layer or the metal layer that has improved wear resistance for the suitable coating of the enhancing ring 24 of Purified Steel, the hard coating of high performance thin film for example.For example be the titanium nitride of vapor deposition (TiN) coating or thermal spraying coating.Directly contact under the situation that strengthens ring 24 at steel roller 12, the contact surface of roller 12 can be provided with same or analogous coating.
In order to safeguard roller 12 and the framework that is connected them, support ring 4 can have can be from the inside of pylon 6 approaching platform (not shown).
